SIGNL4

SIGNL4 is a mobile alerting and on-call duty management service that transforms emails, webhooks, and IoT events into reliable push, SMS, and voice alerts with acknowledgement tracking, escalation, and team on-call scheduling. The platform provides both an inbound webhook for sending alerts and a REST API for managing alerts, statuses, annotations, and team data. Authentication uses a team or webhook secret embedded in the URL path or supplied via the X-S4-Api-Key header.
